We know the dinosaur are the strongest creatures on the continent in ancient times. At that time, there was no human beings yet. Dinosaur almost all creatures. At the end of the Cretaceous, that is, 65 million years ago the dinosaur and some creatures were all extinct. Why and how dinosaur will disappear. Scientists have been exploring this topic for centuries.

The very last non-avian dinosaurs are a different story. Their ranks included some of the most famous and beloved dinosaurs –Tyrannosaurus, triceratops, ankylosaurus, pachycephalosaurus, and more. And even though the global climate was starting to cool and warm seas that once washed over vast expanses of Earth’s continents were beginning to recede, there was no sign that dinosaurs were about to exit the evolutionary stage. They had already been through millions upon millions of years of shifting continents, fluctuating climates, and one mass extinction, around 200 million years ago, that removed the competition and allowed dinosaurs to flower into the fantastic forms that have so tenaciously sunk their claws into our imagination.
